Abstract
White granulated sugar and high fructose syrup are dissolved in water; filtration is carried out to remove undissolved substances; then, the water content in the syrup is removed by a continuous vacuum film sugar decoction device; the remained massecuite is shaped by a single crystal model to directly obtain single crystal rock candy. The making time from the white granulated sugar and the high fructose syrup to single crystal is short; food additives do not need adding; the single crystal directly made from raw sugar has the characteristics of pure taste, high transparence, uniform magnitude of production specification and high product output rate; theoretically, single crystal rock candy with the purity of 100% can be obtained from the raw sugar.
Description
Technical field
The present invention relates to a kind of table sugar production method, particularly a kind of transparent rock sugar production method.
Background technology
The production method of existing monocrystal rock sugar is: the filtering sugar solution by using that white sugar is fully dissolved into liquid glucose → dissolve is removed in the liquid glucose suction vacuum crystallization jar after insolubles → filtrations, this moment, liquid glucose was a supersaturated solution, pol is 70-73Bx, temperature is 65-75 ℃, and vacuum tightness is 80Kpa, adds complete granulated sugar crystal simultaneously and lets alone slowly to grow up as seed, through behind the 6-9d, the weight of every sugar is finished product when being about 6g, take off honey, screening again, can pack and dispatch from the factory.By this technology produce single crystal, because every in the granulated sugar seed that adds is in different growth conditionss, sugar concentration during as crystallization, differences such as massecuite convection current situation and method of operating and cause the product size inhomogeneous, out-of-shape, product colour is inconsistent, longer with the time, the part conversion takes place in liquid sugar inevitably simultaneously, makes the productivity of product not high, and general is 85%--90% only.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, provide a kind of to people and directly produce genuine ground single crystal transparent, productivity height and do not add foodstuff additive and transparent single crystal crystal sugar production method that Production Time is short with raw material sugar.
Technical scheme of the present invention is to realize like this.
1, a kind of transparent single crystal crystal sugar production method is characterized in that
The white sugar of a, raw material composition 92%--95%, the high fructose syrup of 8%--5%.
B, production technique
The water that in raw material sugar, adds 20%--40%, heating is also constantly stirred, make fully dissolving of sugar, when liquid glucose is heated to 103 ℃--110 ℃, concentration is for wanting static 1--3 minute after the 70%--85% liquid glucose boiling, white sugar is fully dissolved, liquid glucose after dissolving filters by mesh screen immediately, liquid glucose after the filtration enters the syrup basin, the liquid glucose temperature is 105 ℃--110 ℃, concentration 75%--80%, the inlet of bottom when sending into the heating of snakelike copper pipe quantitatively by the piston-type sirup pump, liquid glucose in the heating tube is constantly vaporized, form liquid-vapor mixture, rise along heating tube, in uphill process, still continue evaporation, and pressure reduces sharply expands volume, lift velocity is more and more faster, go out from upper orifice at last, liquid glucose by serpentine heating pipe at utmost point short period of time internal heating to 130 ℃--150 ℃, concentration is 90%--98%, this moment serpentine tube heating chamber internal heating vapor pressure maintenance＞90-810Kpa, concentration is to the liquid glucose of 90%--98%, enter the upper entrance of film under vacuum sugar-cooker, liquid glucose is along with the centrifugal force of the rotor generation of high speed rotating, evenly trickle down in the vertical type cylinder inboard wall and flow down from the top along the film of heating inner-wall surface with 0.5-3mm thickness, cylindrical shell is to heat with jacket steam, the rotor at cylindrical shell center is equipped with five groups of blade scraper plates from top to bottom, blade is rotated outside centrifugal force and outwards stretches with cylinder inboard wall and be close to, the sugared film that flows down is vaporization rapidly by heat exchange, steam is discharged continuously by vacuum system, and syrup falls into the cylindrical shell bottom when enduring concentration 90%--99.5%, is cooled to 90 ℃--100 ℃ of sugar grains that form neat homogeneous through special monocrystalline mould, sell through the i.e. packing of cooling again
Technical process heating → dissolving → decon → filtration → heating → concentrate → cool off → enter model → crystallization → finished product → packing.
The specification size and the shape of described monocrystal rock sugar grain are decided by special mould, and the material of its mould is metal or alloy or nontoxic high utmost point engineering plastics.
It is 120 orders-150 orders that back liquid glucose mesh screen is dissolved in described filtration.
Principle of work
The water that in raw material sugar, adds 20%--40%, heating and continuous the stirring are fully dissolved sugar, immediately liquid glucose is filtered with mesh screen, pour the liquid glucose after filtering into the syrup basin, after liquid glucose temperature concentration reaches requirement, send into the bottom inlet of serpentine tube heating chamber quantitatively by the piston-type sirup pump, liquid glucose in the heating tube is constantly vaporized, form liquid-vapor mixture, rise along heating tube, in uphill process, still continue evaporation, and pressure reduces sharply expands volume, lift velocity is more and more faster, go out from upper orifice at last, liquid glucose enters the upper entrance of film under vacuum sugar-cooker, along with the centrifugal force that the rotor of high speed rotating produces, evenly trickles down in the vertical type cylinder inboard wall, flow down with certain thickness film from the top along the heating inner-wall surface, cylindrical shell is that the rotor at cylindrical shell center is equipped with the blade scraper plate from top to bottom with the jacket steam heating, and blade is rotated outside centrifugal force and outwards stretches with cylinder inboard wall and be close to, the sugared film that flows down is vaporization rapidly by heat exchange, steam is discharged continuously by vacuum system, endures the syrup that concentration acquires a certain degree and falls into the cylindrical shell bottom, is cooled to suitable degree, through special monocrystalline model, and form the sugar grain of neat homogeneous.
The utility model is made monocrystal rock sugar with tradition and is compared, and its advantage is: the Production Time from the white sugar to the monocrystalline has shortened tens of times; Because manufacturing time is very short, so not must add the foodstuff additive of whitening agent, SYNTHETIC OPTICAL WHITNER and so on, just directly use raw material sugar, produce monocrystalline genuinely, taste is purer; Raw material sugar is white sugar, high fructose syrup (honeybee sugar is main component), and particularly high fructose nutritive value is higher; Transparency is quite high; Product specification size homogeneous, neat, regular has very high quality standard; The rate of output height of product, theoretically, a raw material sugar can obtain a product, promptly produces monocrystal rock sugar 100%; Production cost reduces greatly.
